excellent product, but longer posts would be better

This is an excellent product. The nice full size post is perfect for taking up some of that bridge play you get on older or worn bridges, and the fine, and very nicely matched threading on the thumb wheels, and top notch plating make for super firm and smooth combo. Nice! All in all, an excellent choice...but measure your bridge height 2x before you set your posts for your SG type project.

funny thread

These will only work on import guitars with metric bridges, and in most cases they will only work when both the thumbwheels AND the bolts are exchanged. Gib...n bridges are made for 6-32 bolts/wheels, and M4 is too big for US bridges. Stewmacs' bolts are M4 x 0,75, which is a highly unusual thread, as regular coarse pitch for M4 is 0,7. Overall quality is good, but measure before you buy.

Could be much better

I used the thumb wheels on the org SG posts and found them to be very loose. Not wishing to make more work for myself I opted to use what I had before. Maybe you need to state that you need to use these posts & thumb wheel's together and not mix with org Gibson fittings.
